linux环境安装python-pip
参考：https://blog.csdn.net/u013372487/article/details/51726002
1、通过wget方式安装
# wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate #不检查证书，尽量避免使用(某些情况下加入no-check-certificate 即可成功安装)
# python get-pip.py
# pip -V
pip 19.1.1 from /usr/lib/python2.7/site-packages/pip (python 2.7)
2、添加yum源安装rpm包
1 添加epel源
2 # vim epel.repo
